In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f
Since the introduction of Edison’s lightbulb over one-hundred years ago, humanity has struggled to keep up with electrification for all. With global attention now aimed at sustainable energy production, the struggle becomes more complex by not only obliging energy access, but access to clean energy. The concept of microgrids has been promising for filling in the demand, but not quickly enough to m
Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes. Here we attempted without success to visualize the pr
G protein coupled receptors (GPCRs) is the largest superfamily of membrane proteins and convert a multitude of extracellular signals and turn them into intracellular responses by binding and activating just a few G proteins. The mechanism for activation is very conserved and is likely to be similar for all GPCRs and G proteins, but how a vast amount of GPCRs selectively couple to specific G protei
2016-2018, a national user-led organization within the psychiatric field in Sweden established a partnership-based model regarding the implementation and management of peer support within psychiatric health care units. This study was based on a user-led organization and a psychiatric health care organization about to initiate such a partnership. The aim was to examine how these parties constructed
In this study, the extraction and isolation of xylan from milled oat hull materials was investigated. Alkali extraction by 2 M sodium hydroxide at 40°C overnight was applied. The yield of extracted xylan was 5%. The extracted xylan was isolated from the extraction mixture by ethanol (99.9%) after neutralization and its purity was checked, resulting in a66% pure product. The semi-purified xylan was
Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. I den här studien vill vi strukturera och analysera observationer av huvudsakligen svavelpartiklar positionerade i stratosfären från naturliga och möjligtvis mänskliga källor, med hänvisning till va
Applied Machine Learning in Steel Industry – Examination of possible applications of machine learning for SSAB Oxelösund In modern industry there are high demands for increased resource efficiency that in part are motivated by the stronger competition on the global market, as well as by the societal necessity for a more sustainable industry. This master thesis project examines applied machine lear
I detta arbete återgår författaren till grundtekniken och undersöker hur detta påverkar spelet. Ämnen som tas upp är vibrato, stråkteknik, koordination och styrka i vänsterhand samt hur dessa korrelerar med varandra.In this project the author goes back to basics and revisits old exercises to see how this impacts the playing. Subjects as vibrato, bow technique, coordination and strength in the left hand is discussed.
Distribution is a part of the supply chain and refers to the steps taken to move and store a product from the supplier stage to the customer stage in the supply chain. Direct shipment is a concept within distribution and refers to shipping direct between a supplier and a retailer or customer. Distribution is considered a key driver for overall profitability of a company since it directly affects b
The Russian state-funded news media RT, formerly Russia Today, has since its start in 2005 created a reputation for acting as Kremlin's propaganda machine and part of Russia's political hybrid warfare. Previous research indicates that RT actively conducts psychological influence operations with the aim of legitimise Russia’s politics among the readers. By adopting a theory-developing appro
Bara var femte ung vuxen som cyklar i Malmö använder cykelhjälm, trots att vi alla känner till farorna som det innebär. Hur kommer det sig att det är så socialt accepterat att ta den här specifika risken? Vad är det som formar vårt beslut att inte använda cykelhjälm? I den här studien närmar vi oss de underliggande attityder som folk ibland hänvisar till när de försöker svara på frågan “varför anv
In Sweden, wind has been recognized as a necessary power source to fight climate change. But the expansion of wind power is associated with conflicting interests. The permit process to build and operate wind power plants is often described as inefficient and complex, with long lead times. This study investigates possibilities for how the Swedish permit process for wind power can be streamlined.
Bakgrund: Nästan varje dag diagnostiseras ett barn med cancer i Sverige. Barncancer drabbar inte bara barnet utan även resten av familjen. Sjuksköterskan spelar en central roll i omvårdnaden kring barnet och familjen och behöver kunna möta varje individs behov. Syfte: Att undersöka föräldrars upplevelse av information och kommunikation med sjuksköterskan när deras barn vårdas för cancer. Metod: En
In the last decades, scholars, managers and consultants have shown increased interest in identifying the characteristics of high-performance organizations. Searching for ways to improve organizational performance and respond to a growing demand for quality products and services in a rapidly changing environment, this subject is of special interest of managers in both public and private organizatio
This thesis aims to analyze how authors who write books for young adults are presented on their publishers’ website. By analyzing the textual presentation of the authors the main objective is to answer these questions: are there any reoccurring aspects in the presentations? Can you tell that the authors write for young adults? Are there any differences or similarities in how the male and female au
Problem description: Warehouses and warehousing operations are often considered as some of the most crucial elements in a company's supply chain, and often stand for more than 20 percent of a company’s total logistics costs. The actual size of these costs are, together with most of the costs related to warehouse operations, mainly consequences of the decisions made when designing the warehouse
Unmanned Aerial Vehicles (UAVs) provide a flexible method for acquiring high-resolution imagery with relative simple operation and cost-effectiveness. This technology emerged 30 years ago and it is widely used by commercial, scientific, and military communities due to its versatility. However, new technology brings new challenges. One of them is the radiometric accuracy of the UAV imagery. Radiome
